Abstract
An aircraft engine starter assembly provides for liquid cooling of the clutch assembly and overrunning engine by integrating a pitot pump in the system. The system includes a starter motor, a torque transfer connection, a clutch assembly and the pitot pump. The torque transfer connection is adapted to be coupled to the aircraft engine. The clutch assembly is coupled to one of the starter motor or the torque transfer connection. The pitot pump is coupled to one or both of the torque transfer or the clutch assembly via a first oil line and a second oil line. The pitot pump comprises a pitot tube in fluidic communication with an oil reservoir for the delivery of oil under pressure to lubricate one or both of the torque transfer or the clutch assembly.
